4.8 is the answer I’m pretty sure
Option B: 21.3 in is the length of AB
Explanation:
The equation is 
To find the length of AB, let us equate,
Substituting the value for sin 25°, we get,
Dividing the values, we have
Thus, the length of AB is 21.3 in.
The correct answer is Option B.
Answer:
39%
Step-by-step explanation:
Let's find the answer by using the following formula:
selling price=(paid price)+((paid price)*(percent markup)) which can be written as:
percent markup=((selling price)-(paid price))/(paid price)
percent markup=(27.80-20)/20
percent markup=0.39=39%
In conclusion, the percent markup is 39%.
Probability of winning = 0.6 , Probability losing = 1-0.6 = 0.4
Expected value = 50(0.6) - 1(0.4) = $29.6
The interpreation of this is that if you play many times you would expect a profit of $29.6.
